What does a world without gender inequality look like? Realising this vision requires inspiring and mobilising social change. But what would indicate we are on the right track - and how will we know when we get there? Gender-sensitive indicators and other measurements of change are critical - for building the case for taking gender (in)equality seriously, for enabling better planning and actions, and for holding institutions accountable for their commitments on gender. This Cutting Edge Pack hopes to inspire thinking on these questions - with an Overview Report outlining key issues, a Supporting Resources Collection providing summaries of key texts, tools, case studies and contacts of organisations in this field, and a Gender and Development In Brief newsletter with three short articles on the theme.
